The Colts are holding a Wednesday morning news conference at the Colts' training complex.

Clark, 35, played last season for the Ravens and caught 31 passes for 343 yards and three touchdowns.

Clark was signed to a one-year contract in August after tight end Dennis Pitta fractured and dislocated his hip during training camp, but his playing time ended when Pitta returned at the end of the season.

He set Colts franchise records for the most career receptions (427) as a tight end and receiving touchdowns (46) by a tight end. He finished second overall in receiving yards (4,887) for a tight end.

Clark set tight end single-season team records with 100 catches for 1,106 yards in 2009 and 11 touchdowns in 2007.

Clark had 64 receptions for 847 yards in the postseason, both of which are NFL records by a tight end, while his four touchdowns are tied for sixth.

During the Colts’ championship run to Super Bowl XLI, Clark posted the highest receiving-yardage total (317) by an NFL tight end in a single postseason since the AFL-NFL merger in 1970. His 21 receptions ranked second.
